Title: Path changeover method for ring network
Inventor: NARUSE YUICHI
IPC: H04L12/437
Filed: 1994-06-27
Abstract: PURPOSE:To prevent dissidence for one circulation time by allowing a specific node on a ring to confirm a ring circulation time after path changeover, allowing the specific node to inform a ring circulation time to a concentrator after path changeover and allowing the concentrator to switch the path at this point of time. CONSTITUTION:A line changeover switch 404 receives a notice of the arrival of a delay sum cell from a cell class discrimination section 401 after the notice of desired participation or release of a terminal equipment connected from a participation/release desire detection section 405 and receives the notice of the arrival of a notice cell finally, then the path changeover for participation or release is executed. Then a delay difference measurement 402 measures the interval till a same cell arrives to measure the delay difference between a concentrator internal path 411 and a terminal side path 412 and the delay is informed to a delay write section 403. In order to avoid the difference between the actual delay and the written quantity, after the reception of a notice from the participation / release desire detection section 405, the section 403 executes the write upon the receipt of the notice of the delay sum cell from the cell class discrimination section 401.

Title: Nonflammable rope
Inventor: SAWAKI TOSHIRO
IPC: D07B5/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain a nonflammable rope easily prevented from the covering material fraying at its cut end by treatment during its production process without impairing the flexibility of the covering material and core material. SOLUTION: First, plural number of ceramic fiber yarns 2 are entwined together to form a core material 3. Secondly, during feeding the core material 3 in the longer direction of the rope, an adhesive 6 is sprayed in a straight line fashion via a spray nozzle 7 on the surface of the core material 3. Thirdly, plural number of glass fiber yarns 4 are wound around the chore material 3 and knitted in a netty fashion into a covering material 5. Thus, the adhesive 6 is infiltrated into both the ceramic fiber yarns 2 and glass fiber yarns 4, effecting mutual bonding between the core material 3 and the covering material 5 through the adhesive 6 after dried along with mutual bonding of the respective glass fiber yarns 4. Therefore, even in the case of cutting this nonflammable rope 1 at any point, there is no concern for fraying of the covering material 5 at the cut end.

Abstract: PURPOSE:To eliminate the formation of a high resistance layer on a regrown boundary and the difficulty of a regrowth by disordering the superlattice structure of a superlattice structure clad layer except a stripe by heat treating by means of impurity diffusion from a current narrowing layer. CONSTITUTION:After a current narrowing layer is formed in a buried shape except a stripe on a substrate 1, a clad layer 4, an active layer 5, a clad layer 6 and a cap layer 7 of a superlattice structure are sequentially grown on the substrate 1. Then, the superlattice structure of the layer 4 is then disordered by heat treating except the stripe by means of an impurity diffusion from the narrowing layer. Accordingly, the step of regrowing on a crystal layer having high mixed crystal ratio of exposed aluminum is eliminated. Thus, a high resistance layer is not formed on a regrown boundary and the difficulty of regrowth is eliminated.

Abstract: PURPOSE:To surely prevent a crawler belt from coming off of rolling wheels by providing a returning speed restricting means for restricting the returning speed for a movable rolling wheel to return to its stopping position to a low speed at the time of shifting from a turning traveling to a straight traveling. CONSTITUTION:A movable rolling wheel 42 which was moved downward at the time of shifting from a straight traveling to a turning traveling and which was pressing the center part of a crawler belt 43 downward during the turning traveling, is returned to its stopping position at a low speed by means of a returning speed restricting means at the time of shifting from the turning traveling to the straight traveling. Therefore, it takes a relatively long time for the movable rolling wheel 42 to return to its stopping position and a deformation in the horizontal direction generated on the crawler belt 43 at the time of the turning traveling can be restored during this time. Accordingly, the crawler belt 43 is already restored to its original form at the point of time when the movable rolling wheel 42 returned to its stopping position, without causing the crawler belt 43 to come off of the rolling wheels 41.

Title: Unidirectional optical amplifier
Inventor: KUWABARA HIDEO
IPC: G02B6/28
Filed: 1982-08-23
Abstract: PURPOSE:To provide an optical amplifier itself with directivity and to obtain an economical relay by providing a branch in the direction opposite to the light traveling direction of an optical waveguide or forming a wedgelike optical waveguide which has sudden level difference width in the light traveling direction. CONSTITUTION:Branch optical waveguides 3-5 form an Y shape; light traveling from the optical waveguide 3 enters the optical waveguide 4 almost without any loss and light from the optical waveguide 5 enters the optical waveguide 3 while reduced nearly to half at a branch point A when the optical waveguides 3 and 4 have nearly the same optical waveguiding functions. When Y-shaped branches are cascased in three stages, incident light from a light incidence terminal 6 is coupled with an optical waveguide 8 and amplified. Light from a light projection terminal 7, on the other hand, attenuates before reaching the light incidence terminal 6 because of the loss due to the Y branches. Consequently, the optical amplifier itself has directivity and provides economical relay.
